Electronic distance measuring equipment.

Edm instruments are highly reliable and convenient pieces of surveying equipment and can be used to measure distances of up to 100 kilometers. The light from the laser bounces back to the device and the tool uses the time it takes for the light to return to calculate the distance that the laser traveled. Edm is commonly carried out with digital instruments called theodolites. Normally these used to measure long distances within 100km with their frequency range.

The resulting measurement is often shown on a digital screen on the device. Electronic distance measurement edm is a method of determining the length between two points using electromagnetic waves. The electronic distance measuring equipment is differentiated into three types as microwave instrument infra red equipment and light wave equipment.
